Order Crawfish Allergy Test | Shellfish AllergyA crawfish allergy test measures the amount of specific IgE antibodies in the blood that react to crawfish, also called crayfish. Because crawfish belong to the crustacean group of shellfish, a reaction to them often overlaps with sensitivity to shrimp, crab, and lobster. The test is used to help confirm or rule out a shellfish allergy when symptoms suggest one.
About Crawfish Allergy Test | Shellfish Allergy in Bayamon
Crawfish allergy is an immune response to proteins found in the shellfish, not to the cooking method or the spices used to prepare it.
When a person with a crawfish allergy eats or sometimes handles the shellfish, the immune system treats certain proteins as a threat and produces immunoglobulin E, or IgE, antibodies against them. On later exposure, those antibodies trigger the release of histamine and other chemicals, which cause symptoms that can range from itching and hives to swelling, vomiting, or difficulty breathing.
A blood test for crawfish-specific IgE detects these antibodies in a sample and reports the result as a numeric level. The measurement reflects sensitization to crawfish proteins, but sensitization alone does not always mean a person will have symptoms. Clinicians interpret the number alongside the patient's history, other allergy test results, and the circumstances of any past reactions.
Crawfish are crustaceans, and the proteins that cause reactions are similar across shrimp, prawn, crab, and lobster. Many people allergic to one crustacean react to others, so a crawfish result is often considered together with tests for related shellfish. Mollusks such as clams, oysters, and scallops are a separate group and may or may not be a problem for the same person.
